altaylar2000 Posted March 30, 2021 Posted March 30, 2021 We have been taught that current is the movement of particles. But that doesn't match what it is traveling at the speed of light. I was thinking about it, and it seems that current is wave that behaves like light wave in black body. There is principal of multiple reflection of the wave from the walls of the conductor. This also explains the fact that conductors usually have a glossy surface.

The electrons in current carrying conductor do not move very fast but the electromagnetic waves in the conducter move at the speed of light through the conductor. So a light may turn on almost instantly when switched on but the electrons from the source will take a while to reach the light.

Country Boy Posted March 31, 2021 Posted March 31, 2021 Okay, since your are talking about DC current where do "electromagnetic waves" come into it? Electromagnetic waves do not travel along wires. 1

Electromagnetic waves do not travel along wires. I am not very well versed in electronics so I may have gotten my terminology wrong. This is from wiki: In everyday electrical and electronic devices, the signals travel as electromagnetic waves typically at 50%–99% of the speed of light, while the electrons themselves move much more slowly. My point to the OP was the signal in the circuit travels very fast but the drift speed of the electrons in the conductor is slow.

This is just a speculation and you seem to have spent a lot of time here discussing other matters without visiting this thread. Are you still interested ?

Current is a very general term that refers to transport of charge by charge carriers or transport of energy in electromagnetic fields. There are many complications to discuss.

joigus Posted March 31, 2021 Posted March 31, 2021 (edited) Fiber optics works nothing like electrons in a wire. It's based on total reflection of coherent light at smaller than critical angle at which total reflection occurs. You can experience total reflection on the window of your home. Electrons don't go at the speed of light even in a vacuum, let alone in a conductor, as @beecee said. It seems you're confusing many things here. The black body radiation is in equilibrium with the electrons in it, which is a very different situation to conductivity. etc. Edited March 31, 2021 by joigus minor change in word choice

I believe that it is not electrons that work in the wire, but the wave itself. The same delusion previously existed in Newton's theory of light, that light is supposedly moving particles and energy transfer is carried out due to them.

This thread did not start with sufficient information for a sensible discussion and has IMHO deteriorated since through lack of sufficient OP input. What do you want to achieve from this thread ?

You may have just "discovered" quantum mechanics. Everything everywhere works as a wave. Right? We even have a name for that wave: Conduction band.

Just their photons supposedly flying in a vacuum from this series. They even distorted the very concept of "quantum" for the sake of this, because this is the Planck's term, and he meant by this a portion of the wave during emission and absorption, and not a particle In addition, the concept of long-range action in quantum spin is actually used there, long-range action is generally recognized as anti-scientific obscurantism

But this wave behaviour is quite different from that of optical fibre systems. And, of course, you must then be talking about alternating current or transients. But then there are the electrical engineers' circuit models and physicists' models and chemists' models all for different purposes. And there is conduction current and displacement current And, of course, electrons are not the only current carriers, some are not even physical particles. So pony up and pin down some specifics please. Otherwise we shall be forever in the he-said-this - she-said-that mode.

Quantum mechanics "is trying" nothing of the kind. There are all indications that they are talking about the same model that the ancient atomists and Newton spoke of. This is not only a physical, but also a religious, historical, philosophical and ideological question. Edited April 1, 2021 by altaylar2000
studiot Posted April 1, 2021 Posted April 1, 2021 It is also worth noting that it is possible to have current without voltage and voltage without current, although the two are often linked. This simple fact is often overlooked.
